CVE-2025-11472 is a SQL injection vulnerability identified in SourceCodester Hotel and Lodge Management System version 1.0, specifically affecting the /edit_room.php script. The vulnerability arises from improper sanitization of the 'ID' parameter, which an attacker can manipulate remotely without any authentication or user interaction. This allows an attacker to inject malicious SQL code, potentially leading to unauthorized access to the backend database, data leakage, data modification, or even deletion of critical hotel management information. The CVSS 4.0 score of 6.9 reflects a medium severity, considering the attack vector is network-based with low attack complexity and no privileges or user interaction required. The vulnerability impacts confidentiality, integrity, and availability to a limited extent due to the lack of scope change or system-level compromise. Although no active exploitation has been reported, the public availability of an exploit increases the risk of attacks. The vulnerability is particularly concerning for hospitality organizations relying on this system for managing room bookings, customer data, and operational workflows, as exploitation could disrupt services and compromise sensitive guest information. The lack of official patches necessitates immediate mitigation efforts by users. The vulnerability underscores the importance of secure coding practices such as input validation and the use of parameterized queries to prevent SQL injection attacks.

For European organizations, especially those in the hospitality sector using SourceCodester Hotel and Lodge Management System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to sensitive customer data, including personal identification and booking details, potentially violating GDPR and other data protection regulations. Data integrity could be compromised, resulting in altered booking information or operational disruptions, which may affect service availability and customer trust. The attack requires no authentication or user interaction, making it easier for attackers to exploit remotely, increasing the threat landscape. Given the hospitality industry's importance in countries like Spain, Italy, France, Germany, and the UK, successful exploitation could have economic and reputational consequences. Additionally, attackers could leverage the vulnerability as a foothold for further network intrusion or lateral movement within the organization. The absence of known active exploitation provides a window for proactive defense, but the published exploit increases urgency for mitigation.

1. Immediate code review and remediation of the /edit_room.php script to ensure the 'ID' parameter is properly sanitized. 2. Implement parameterized queries or prepared statements to prevent SQL injection. 3. Apply strict input validation and whitelist acceptable input formats for all user-supplied data. 4. Monitor web application logs for unusual or suspicious SQL query patterns targeting the vulnerable endpoint. 5. Restrict database user permissions to the minimum necessary to limit potential damage from injection attacks. 6. If possible, isolate the affected system from critical internal networks to reduce lateral movement risk. 7. Engage with SourceCodester or community forums to obtain or develop official patches or updates. 8. Conduct penetration testing and vulnerability scanning to verify the absence of similar injection points. 9. Educate development and IT teams on secure coding practices to prevent future injection vulnerabilities. 10. Ensure regular backups of critical data to enable recovery in case of data corruption or deletion.
